IMPRKOVIED `STIREIET-SVVIEEPING- MACHINE.-

The Scheduler-eterne. *c in then Letters Patent and making part of the same' To all whom tfinay concern ,f l

Be it known that I,`ALi,1xANDEn A. tovsaLvr, of thecity, county, and State of 'New Tr'ork, have iliade certain new and useful Improvements du Street` sweeping Machin s;' and I do hereby declare that the following isa full, clear,and exact description ofA the saine, reference being had to the'accompanylng drawing and lett-ers of reference marked there- `on, the same `xdnaking'part of thisspecication, iu

which- H Figure 1 relin'esents a vertical longitudinal section of a streetfsweeping machine with my improvements. Figure 2rep're`sents an end view of the same. Figure 3, a top view ofthe same. i Similar letters of reference indicate corresponding parts in the several figures.

Thisinrention consists in the construction, arrangement, and combination of parts, as hereinafter set i forth.

To enahleothers skilled in 4the art to make and` use my improvements, I will proceed to describe theirdetails and operation. C ,p

A represents the platform, which is supported iu the bearings B B of the-hind axle C, and upon-the fifthwheel and front axle D; and the hind axleGisprovidedwith the usual clutches and clutch-levers for disengaging the hind wheels from their axle when the machine isnot in use, or brought from placeto place or to the place of operation.

`E represents the broom or sweeper, the axle F of which rests in bearings G G, which both are supported' and swing on the hind axlewith their rear ends, and the rotation of said `broom is obtained in the usual way, by means of a gear-wheel, H, upon the hind axle,` anda pinion, I, upon ythe shaftof the broom.

J represents the pan or dirt-receiver, upon which the dii-tis elevated by the broom, and K the dumping'- hox, on` which thedirt collects and is dumped.

The forward end of the pan J is hinged to vertical sliding bars, L L, by means of a fulcrum-bar, L', while its rear end issuspended ontlie shaft or bearings of the Broom, and they said sliding bars L L areattached to stationary vertical bars, M M, secured to the side of the platform, as clearly shown.

The dumping-box K is of semicircular form, has its fnlcrum on the bolts or studs N N of the hangers O O,.which are suspended and secured ou the side of the platform, and l? isa resting-block, against which the Asaid dumping-box stops while receiving the dirt;`

Now, in order to raise or lower the broom and pan and operate the dumping-box together, whenever required,

I employ the windlass @which has the winding-.arbor or shaft R, arranged horizontally in bearings, S S, secn red upon the platform of the machine, -and hasupon 'tlhsaid shaft a hand-wheel, T, and a ratchet-wheel,

U, and upon the platform is'secured a standard V, which supports a pawl, W, arrangedto operate on the said ratchet-wheel, and tothe said shaft R I attach the 'ends' of, three chains or ropes, X Y Z, on each side of the machine, and, the loose ends of the chains'X X,'I

attach'to'the bearings G G .of the sweeper or broom,

the said bearings being provided with propel' hooks or eyes for that purpose. 4

'.The loose 'ends of the. chains YY, I secure tothe fnlcrnm-har L" of the pan J, and the loose ends of the chains Z Z,I attach'to the forward side ofthe dump ing-box, so that, by means of turning the"hand'wheel T, the said chains all wind up upon the shaft It, and raise, consequently, the broom as well as the pan, and turn, also, the dumping-.box toperform the dumping of the dirt; or, ifv the pawl W is disengaged from the ratchet, the pan and broom are lowered, and the dumping-box .turned` in position for operation.

From the foregoing it will be clearly perceivedthat the operation of the machine is greatly simplified, 'and one operator may manipulate the Ina-chine,

I do not claim Athe employment of a windlass in streetfsweepug machines, for raising the broom and4 receiver, ast-his is not new; but having-fully described my invention, l

What I claim therein, and desire to secure by Leti ters Patent, is-v The combination-of the eccentiically-pivoted and .semicircular receiver K, the pan J, adapted to bev raised and lowered, and the rotary sweeper F E, all connected with a windlass, R, byy chains X Y Z, when said partsare arranged as shown, and are constructed to operate substantially as hereindesciibed.4
